Born to a Hadian Major and a Daoese mother, Lisa Aubrook had a strict upbringing very early in her life. Lisa’s mother, headmistress at a private Hadian International School, and father, who was recently promoted to Lieutenant-Colonel following the outbreak of the Hadian Civil War, compelled her to excel in everything she strived in. With her parents’ strict teachings and austere lifestyle, Lisa rarely met, let alone engaged with people her own age. She engrossed herself in academic texts and documents, almost to a religious level, and while others her age would spend time outdoors fiddling with sticks and balls, she would be absorbed in study. She learned mannerisms and formalities, etiquette and speech, nearly everything in those days to impress the grown adults that surrounded her everyday life. And yet she was fascinated with one group of adults in particular: the men that accompanied her father whenever he returned from duty. They were different from the tutors, the maids, the professors and businessmen that visited their estate. These men were brash and unsavory. They spoke with vernacular tongue, disregarded formal manners and roared in exuberant laughter that echoed across the halls. Yet the tales they spoke with great enthusiasm is what attracted young Lisa the most. If it were not for those tales, she would have dismissed her father’s colleagues as nothing more than well-dressed brutes.

It did not take long after for Lisa’s usual routine to sour. She began to slacken. She would lose focus with her endless lessons. She would stare seemingly at nothing and daydream while an opened book lie motionless atop her thighs. Lisa’s father took notice, and decided Lisa would need a change of pace to fix her restless nature. Although Lisa’s mother fought over the issue, she reluctantly agreed to let Lisa’s father enroll her into the Piette State Military Academy. And so at the ripe age of fourteen, Lisa became one of the many cadets to study at the prestigious military institution.

At age sixteen, Lisa joined the Special Informations Agent Program, a recruitment program headed by the State Intelligence Committee to find suitable candidates for espionage and covert operations under their command. With her exemplary skills in logic deduction and libraric knowledge, Lisa was assigned as a cryptographer and partnered with the young upstart Baron Mosse, whom she painfully detested. Baron would later successfully infiltrate a new Unionist cell, to which he would send encrypted messages back to Lisa via carrier pigeon on a weekly basis. For over a year, Lisa served in this capacity whilst continuing her studies within the Academy until she and Baron were withdrawn from the program following the end of their tenure. Lisa was ultimately rejected from joining SIC, but was referred to the Hunter’s Unit where she would put her deduction and observation skills to great use.

Upon her graduation from the Academy, Lisa would quickly rise through the ranks of the Hadian Hunters, achieving the rank of Captain in nearly a year of service, all thanks to her high success rate in finding and neutralizing enemy strongholds. Overtime, she earned the unofficial title of “Raven’s Eye” by her peers from her ability to track down elusive individuals that otherwise would have escaped her colleagues’ gaze. That title however would come under challenge upon encountering a formidable rival among the ranks of the Legion of Terra: Staff Sergeant Eliza Finley.

As the Legion of Terra expanded their operations across the globe, it became more evident that greater specialization would be necessary to fill the demands of fighting in treacherous terrain and inhospitable environments. With plans to expand the Legion into a greater assortment of specialist infantry, three new Legionary Orders were created, effectively doubling the division and subsequent complexity of the Legion’s organization. Of these new orders was the Order of the Marines, elite troops trained in assault and raiding tactics.

Much like their Grenadier cousins, Marines were designed to engage the enemy in frontal attacks using superior firepower and maneuvering, however they held much greater emphasis in small-scale unit tactics and rapid deployment. They operated in dense, limited terrain engaging within close proximity to the enemy, finding exploitations and opening areas of attack through aggressive harassment and skirmishing techniques before spearheading across multiple fronts. Such methods of battle meant a high emphasis on mobility and stopping power. Weapons such as automatic rifles, shotguns, and rifle grenades were often employed by Marines to accomplish this task, and boded well for the kinds of environments the Marines often fought in, ranging from dense towns and cities, island fortresses and entrenched beaches, and even as exotic as jungles and alpine mountains. Fighting in such difficult environments made small-scale unit maneuvers extremely important, a niche the Marines filled exceptionally in comparison to the other Legionary Orders, which at the time emphasized large-scale unit mobilization as their primary tactic.

As such, the Marines had a notable record of defeating numerically-superior opponents in their tenure because of their training and tactics. They excelled at breaking through enemy defenses and disrupting formations for exploitation, as their service with the Marianans showed when they successfully cracked open the seemingly-invincible Elsian Iron Fortress chain. However, their success as aggressive raiders and incapacitators comes at the price of defensive capabilities. Because their tactics require extensive use of mobile, offensive-oriented equipment, much of the Marine’s gear lacks any real defensive capability. Marines are prone to drawn-out firefights, where troops and supplies can quickly dwindle under attrition, and cannot effectively engage in long-range skirmishes or reliably defend against an overwhelming offensive themselves. Marines must constantly be on the move and on the offensive, lest they become the hunted themselves.
